when is it too late to add co2/ does it stress them

[fullmelt925]

Is there ever a point where it is too late to add co2 to flowering plants?
I have added it at the 2 week stage before and still saw the usual benefits from it....

Today I had a bit of an issue https://www.icmag.com/ic/showthread.php?t=284575

And was wondering if adding the co2 this late 22 days into flower, can stress my ladies? I was planning on adding it very gradually.



Ps:i have kept my temps at 75-78f before co2, but usually keep it about 83-85f after I add it....should I gradually up the temp as I up the co2? Same question goes for two weeks out from harvest when I cut it out...should I drop the temps back down?

as co2 is a key part of a plants life i dont think there is ever a bad time to add it to your room...maybe a more experienced member can chime in though...

I would stop it the last few weeks of flowering I've heard it prevents a chemical from forming..

Most people cut it out around 3 weeks from harvest. regardless of CO2, I want my temps no higher than 80. More terpines evaporate at higher temps. You still get benefit from it at lower temps. Good luck. -granger
